PRUSA i3 Isolation Foot (Bear upgrade) - 2040 aluminum extrusion

thingiverse

Here's a clear solution for creating an isolation foot for the corner of the Prusa Bear Upgrade using 2040 aluminum extrusion, designed to work seamlessly with sorbothane isolation pads. To start, you'll need to isolate any vibrations using Sorbothane Vibration Isolation Circular Pads (0.25" thick, 2.25" diameter), available on Amazon at https://www.amazon.com/gp/product/B0042U8P9C/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1. By centering this foot over the joining plates, you can ensure a solid foundation for your upgrade. Adding recessed screw holes allows the foot to sit level and prevents it from shifting due to existing screws.
